8. Charlie Tilson, 21
Tilson has come a long way since missing the entire 2012 season due to a shoulder injury suffered in spring training of that year. The 21-year old will turn 22 on December 2nd and already has 145 plate appearances at the Double-A level despite missing a whole season. The Double-A jump was not kind to Tilson as he saw his OPS drop from .770 at Palm Beach to just .593 at Springfield. Also, his strikeouts were up in 2014 as his K rate was around 19%, up from roughly 14% in 2013. With the bad comes some good as he did a better job of squaring up on the ball and making solid contact this past year, raising his line drive % to around 16%, up from 9%. Tilson flashes above average defense in center field and has above average speed. He could hit at the top of the lineup if he can get on base more and limit the K’s. I would expect Tilson to return to Springfield in 2015.
